Abstract: A power converter with slew rate detection is disclosed. A power converter comprises a plurality of phase circuits coupled to a regulated power supply line via corresponding ones of a plurality of inductors. A first control loop generates, using digital samples and based on comparisons of a reference voltage to a voltage on the regulated power supply line, a first plurality of control signals. A second control loop, using the digital samples, generates a second plurality of control signals based on a rate of change of the voltage of the regulated power supply line. The second control loop causes the first control loop to control the plurality of phase circuits in response to detecting that the rate of change is within a specified range, and causes the second control loop to control the plurality of phase circuits, in response to detecting that the rate of change exceeds the specified range.
